A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
Passive electronic component which reduces current flow in a circuit, dissipating power as heat.
A semiconductor component used for amplifying or switching electrical signals. Use this tag for discussing transistor circuits.
Identifies the size and nature of information held by a variable in a program. It is language-dependent. Examples for C/C++ include: `int`, `float`, and `char`.
Typically refers to a specific type of device which allows raw serial communication with a PC via USB.
used to convert a serial string of bits into parallel data, or vice-versa.
generated during the compilation phase, often due to problems with invalid syntax and/or types. Not for errors during the uploading or execution phase.
used to generate a PWM (Pulse Width Modulation) output signal on compatible pins.
a vibration that propagates as a typically audible mechanical wave of pressure and displacement, through a transmission medium such as air or water.
The process of finding and resolving problems ('bugs') in a hardware and/or software system.
An electro-mechanical device for detecting angular position and/or motion.
if your question is related to signal processing techniques (within the Arduino's capability).
A gps library providing: position, date, time, altitude, speed and course
Interrupt Service Routine. A function which gets called in response to an interrupt signal.
A variable in C/C++ which stores the type and location of data in memory.
should be used for questions regarding the selection of components, deciding functionality, and other issues that may come up during the early stages of a project.
Volatile memory used by Arduino programs for storing variables and other data at runtime.
A datatype in C/C++ which stores a single-precision floating point number.
also known as ANSI/TIA/EIA-485, TIA/EIA-485, EIA-485 or RS-485, is a standard defining the electrical characteristics of drivers and receivers for use in balanced digital multipoint systems. The stand…
A multiplexer lets you select one signal out of a group of (typically) 8 or 16, for both input and output purposes. Use this tag for discussing multiplexer chips.
Port-mapping refers to directly accessing the hardware registers (ports), in particular the input/output ports. Use this tag for discussing direct port access.
a keyword used when declaring a variable that keeps the data in flash instead of copying it into SRAM. It is part of the `pgmspace.h` library. Use this tag for discussions about using this …
